A new type of peg that makes it easier to change strings!

Either that or most guitar shops stock string pegs, Just ask at the counter .. .If they don't have them and can't get any in then they are not a real guitar shop in my opinion

The neck may require adjustment, but would recommend taking it to a luthier or using a guide like raeguitars to talk you through it. Depending where it is on the fretboard that buzzes, the nut may require replacement/adjustment. I've had all these problems in the past and the above tutorial helped me fix all of them.
